VACUUM APPARATUS FOR STRIIPPING CARDS,

Application filed December 10, 1920. Serial No. 429,741,

(GBANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1318.)

7 '0 all whom it may concern:

Be it known that I, PAUL KESTNER, engineer, citizen of the French Republic, residing at Boulognesur-Seine, Department of the Seine, in France, and having P. 0. address 113 Boulevard de Strasbourg, in the said city, have invented certain new and useful Improvements in Vacuum Apparatus for Stripping Cards (for which I have filed applications in France, 21st November, 1919, and 3d March, 1920; vBelgium, 14th July, 1920; Germany, 24th July, 1920; Nether lands, 27th September, 1920; Switzerland, 27th September, 1920; Great Britain, 10th November, 1920) and I do hereby declare the scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to improve vacuum apparatus for stripping cards, such as described, for instance, in the French Patent'No. 1412285 of 6th April, 1912, and in its addition of 12th June, 1918.

Primarily, the invention has for its object the provision of a stripping apparatus in which a support, coextensive with the axial length of the carding elements, is hingedto the frame of the machine and on which support travels the carriage of the suction nozzles to traverse the carding surfaces. This'support, together with carria e and other parts mounted thereon, can e turned to and from operative positions relative to the carding elements, and after the first installation of the device no further ad justment of parts is required to insure proper'registration of the nozzles with the carding surfaces. The invention also has other objects which are pointed out here- 'inaften,

showing in dotted lines theposition of the apparatus during the sharpening of the teeth of the main cylinder.

Figure 2 is a vertical section showing the suction box, the suction nozzles and their r i'es of throughways.

Figures 3 and 4 show a front view of the arrangement of the apparatus on a carding machine, theset of fingers or studs and the means for turning back the apparatus to allow of removing the sheet-metal plate of the cylinder.

Figures 5 and 6 illustrate the clutching and-disconnecting of the carriage.

Figure 7 shows the finger fixed on the chain as well as therunner or slide which ensures the translation of the carriage.

Figure 8 shows a side view in full lines of the apparatus in working position, and in dotted lines of the apparatus after belng swung aside, during the sharpening of the teeth or the main cylinder for instance, and shows also the method the carding machine.

Figure 9 is a view from above of the apparatus showing the arrangement of the supports.

The apparatus comprises a longitudinal support or frame 1 having at each side a longitudinal groove 2, preferably triangular in shape, and a carriage 3 having grooves 101": the same shape as those of the frame and in which are fixed adjustable balls or rollers 5 to permit the carriage to roll on the frame 1. v

The suction box 6 is attached at 7 to the carriage 3 on which it is adjustable by The suction nozzles 11 and 12 are mounted in the nozzle carriers 9 in which they can slide to allow of their being adjusted.

The nozzles carriers 9 are provided with plugs 13 and 14: adjustable so as to put into communication successively or simultaneously the suction orifices of the nozzles 11 and 12 with the pipe 10, or to cut off this of fixing it on communicationby displacing in one direction or the other apertures 17 formed in these plugs. 1 I

The supports 18 and 19 carry the frame 1, to which they are fixed by means of feet bolted 'or'sc'rewed to each end of the frame. These members 18 and '19 themselves carry two slotted arcuate brackets 20 and 21 Fig. 1 in which studs 22, 23,24 and 25 are slidable, said studs being adapted to engage the plugs 13 and 14 and put the suction nozzles 11 and 12 into communication with the suction pipe 10.

The supports 18 and 19 have bosses in which shafts 19 and 18' are adjusted and fixed. These shaftsreceive supports 26 and 27 respectively (Figure 4) on which the frame lisfixed and permit of turning back the apparatus into the position indicated in dotted lines without disarranging it (Fig. 1 The supports 1.8 and 19 are fixed on the counter supports 28 and 29which are themselves fixedeither directly upon the cover plate of the doflingcylinder 30 or on the cheeks .31 and32, Fig. 3, of the frame of the'doife-rnear the axis of the'latter.

The frame 33, Figs. 5 and 6, encloses two pinions 34 and actuated b another pinion 36 which is itself driven y means of a chain 37 and a pinion 38 keyed on the shaft Ofthe dofler. Thistrain of pinions gives the movement of translation to the carriage through the intermediary of the chain 39 which is driven by a'pinion 40 keyed on the shaft ofthe pinion 34. Another pinion 41 (Figure '3) mounted at the side opposite to the driving gear is furnishedwith an adiustable bearing" 53 to maintain the chain in its horizontal and taut position.

Thedriving and stopping mechanism of the carriage 3 is constituted as follows:

The pin1on35 is keyed on a shaft 42. The

' "pinion 34 is loose on a spindle 43 and can only be actuated "by the latter when the clutch member 44 is pushed by'the spring 45 and engages its spurs 46 in the recesses 47 of the pinion 34. This driving device starts the carriage and automatically stops her:

it whenthe stripping operation is finished.

The carriage3 is set in motion by the chain 39 which draws it along by means of the stud 48 fixed on one of the links of the chain and the slide'49 fixed under the carriage 3. The uncoupling fork '50 also fixed on the carriage.

- The whole apparatus is inclosed in a casing 52 without interfering, however, with tll e transverse movements of the suction noz- 7. es. mechanism from dust or fluif which might clog it'and put it out of order. I

The apparatus acts in the following man- The apparatus as shown in F 3 is assumed to be at rest. The uncoupling fork .der to the other.

This arrangement. protects all the 50 (Fig. 5) having acted on the side of the clutch member 44 has displaced the spurs 46 from their recesses 47 and the ipinion 34 through the slide 49 and raws it along, thev fork 50 following the movement ofthe carriage, disengages itself and permits the clutch member 44 to engage its spurs 46 in the recesses 47 under the pressure of the spring 45. I i T The pinion 35 is rotated continuously through the pinions 36 and 38 and drives the carriage from one end of the main cylin- In turning the hand wheel 51to clutch the apparatus as has just been explained, the

carriage advances a little, and this causes one of the plugs 13 or 14 to bepush'ed by one of the fixed studs 24 or 25'and thus estab.

stroke, one of the fixed studs 22 01*93 pushes the plug which putsthe suctiongpipeinto communication with the suctmnnozzle that strips the other cylinder in the-returnstroke. The carriage then comes back toward its" starting point, the slide 49 being devisedso that the fingers or studs 48fixed onthe chain imparts a to-and-fro movement to the car-,

riage while the chain 39 turns always in the same direction until it reaches the Rendof the stroke. When the carriage arrives near the end of the stroke (Fig. 3) one of the fixed fingers or 'studs'24 or 25 pushesthei plug which cutsfloff completely all communication between the suction nozzles and f the suction pipe. The carriage 3 ist hen stopped automatically (Fig. 5) by the un cou )ling fork. 50 engaging a projection on the clutch member 44 thus diseng aging the spurs 46 from their recesses 47. The. can

riage is stopped and the apparatus is ready for a fresh operation.

Vhen the carriage is near the end of'its The apparatus shown in Figs. 8 and '9 is constituted by a screw 53 preferabl having two threads, a tube 54 surrounding t escrew,

a carriage43, with a valve member 55' which slides on the tube. The 'carriageis structed so that'fit receives the suction 'noz} zles 12 and Hand the shutter 55. ifThe'suc} 'tion nozzles and the valve meniherare put into communication with the vacuum pump sheet-metal cover plate 64 of the doli'er.

The supports 56 and 57 carry also a tailpiece 65, the object of which is to prevent the apparatus falling backwards when it is swung back. This tail-piece abuts against a plate 66 of the counter-support, and thus holds the apparatus in the position shown in dotted lines in the drawing.
